We recently experienced a problem with our Norther Lights Generator leaking oil when not in use. There were no signs of leakage around the drain plug/hose area for changing the oil. We suspected and this morning Stuart Yacht has confirmed there is a small rust hole in the bottom off the oil pan (see pictures). There was no way to confirm the problem until the genset was removed from the boat. I understand some of you have put a little HVAC filter material in the genset air intake to reduce the chances of salt water intrusion, I will be doing that also. Not sure there is anything else that can be done from a preventive standpoint.
